In any of the other SB runs, when have the Pats rested their starters for more than a half?
there's a great business school case that is still taught about the Challenger in '86.
I don't want to ruin the ending for you, but the crux of the exercise becomes clear when you look at the O-ring data. If you look only at the data from the launches that had the common outcome (i.e. successful launch), you come to the conclusion that the everything is good to go with the launch.
Then only a small percentage of the best students overlay the O-ring data of the failed launches and realize something is terribly wrong. They would never launch.
So in football, if you say "hey look, when did BB ever rest his starters in 01,03,04?" you will invariably start ridiculing other posters with totally invalid data. He always wins superbowls without resting his starters, right, 100% of the time.
hint: throw in 06 (rodney) and 09 (welker) - its the O-ring data you aint looking at.
